ummm no it really isn't (can we not learn from previous seasons).Given that United are 8 points behind and Van Gaal is there until at least the end of the season, and given that we'd have to go on a really poor run to lose that advantage, this could actually be the result that all but seals our Champion's League campaign for next season.
Let's just take it 1 game at a time and see where we end up (nothing is "sealed" yet).
